Used primarily as a component in high-performance fuels due to its excellent anti-knock properties. Its branched hydrocarbon structure contributes to a high octane rating, making it valuable in aviation and racing fuels where engine efficiency and stability under pressure are critical. It may also serve as a solvent in specialized industrial applications where low reactivity and controlled evaporation rates are required. Due to its stability and low polarity, it is occasionally used in calibration mixtures for gas chromatography and in research settings to study combustion kinetics.
